Container seal
The first is the use of the "container" concept in transportation to produce a container seal. The rotating and stationary parts of this seal are pre-assembled as a whole before installation. After inspection and pressure testing, they are set on the shaft in the shaft seal box, fixed on the shaft with set screws, tighten the gland bolts, and remove the container. With the positioning piece, the mechanical seal can be located in a parallel plane working state and transferred. This not only facilitates assembly, but also ensures assembly quality. Welded metal bellows mechanical seals homogenize such a set of static rings, moving rings, bushings and glands and auxiliary seals. A pre-assembled, inspected and tested seal assembly is used before installation to easily ensure installation and Assembly quality. This cartridge seal has the following characteristics:
(1) It is not necessary to measure the working length of the seal during installation;
(2) The axis can be adjusted at any time;
(3) There will be no leakage problem at startup, because the seal has been tested in advance;
(4) It is only necessary to tighten the sealing cover bolts when installing, and the assembly quality is easy to ensure;
(5) Before sealing or installation, protect the sealing surface from contamination or damage due to operating errors;
(6) Machines and equipment can be readjusted after thermal expansion;
(7) The center can be determined by cooperation;
(8) It is easy to take out the seals for cleaning and inspection without disassembling the pump equipment. The API682 standard recommends that all mechanical seals use cartridge mechanical seals.
